Cell cracks appear as dark, discolored, broken lines or areas in electroluminescence (EL) images. The module could produce less energy if these cracks restrict the flow of current through the cell.

There is EVA (plastic) film underneath that cracked glass (between glass and solar cells), so in some cases cracked panels can tolerate moisture long time even if you don"t repair them at all.
